Microwave Remote Sensing of China Seas and Coastal Zones and Application in Ocean Renewable

Resource Evaluation (ID. 10412)

1 Project's partners

2 Project's objectives

(1) To investigate winds, waves, currents and other mesoscale processes (internal waves, fronts, eddies, etc) in China Seas with multiple satellite sensors (SAR, Altimetry and Scatterometry) from China, ESA and TPM.


(2) To develop ocean wave energy resource evaluation method with remote sensing data. To get ocean wave energy resource distribution map of China Seas.

Global wave energy resource map


(3) To analyze coastlines changes in the China coastal zones especially Yangzi River Estuary due to reclamation.

Coastlines changes of Hangzhou Bay


(4) To prepare CFOSAT by using SAR and Scatterometry data. A wave-scatterometer spectrometer (SWIM: Surface Waves Investigation and Monitoring) and a scatterometer (SCAT) are on board CFOSAT. It is scheduled to begin orbital operations in 2015.
